Predictive approach to environment provisioning

ABSTRACT

Embodiments of the present invention provide methods, systems, and computer program products for building an environment. Embodiments of the present invention can be used to allocate resources and build an environment such that the environment is built when a user is prepared to test one or more portions of code in the environment. Embodiments of the present invention can be used to reduce the “lag time” developers experience between waiting for the code to be built and for resources to be provisioned, and can also provide a less costly alternative to maintaining and operating dedicated environments.

FIELD OF THE INVENTION

The present invention relates generally to the field of test environments, and more particularly to provisioning resources for test environments.

BACKGROUND OF THE INVENTION

A computer software program needs to be evaluated to determine whether it achieves its particular or desired purpose. Generally, software testing is used to expose problems with the software to alert software engineers to debug the code in the software causing problems. Test environments are used to mimic the intended software and/or hardware environment in which the program will be deployed to ensure the program will perform its desired purpose for the end user.

Typically, after code is written for a software program, the software engineer must wait for the code to be “built”. In the interim, the software engineer must build the software test environment to test the code and determine if it performs as desired. For example, a team of software engineers could use DevOps, a methodology of software development that helps an organization to rapidly produce software products and services, to provision resources for building test environments by selecting various pre-requisites and co-requisites that need to be installed to run the tests. Given the complexity of the environment, the provisioning could take hours to complete, and only then could the software engineers begin testing. Thus, software engineers can experience “lag time” between waiting for the code to be built and the creation of the test environment. In other instances, there could be dedicated environments already set up but are not being used.

SUMMARY

Embodiments of the present invention provide systems, methods, and program products for building an environment, such that the environment is built when the user is prepared to test the one or more portions of code in the environment. In one embodiment of the present invention, a method is provided comprising: identifying a coding task to be performed by a user involving one or more portions of code for a software program; identifying resources with which to build an environment for the coding task based, at least in part, on one or more areas of the software program associated with one or more portions of code; and calculating a time at which to start building the environment, such that the environment is built when the user is prepared to test the one or more portions of code in the environment.

DETAILED DESCRIPTION

Embodiments of the present invention recognize the need for ways to provide more efficient allocation of resources for building an environment. Embodiments of the present invention provide systems, methods, and computer program products for predicting a necessary environment and ensuring the environment is available to be used for testing when a developer's build is completed and ready to be tested. Accordingly, embodiments of the present invention can help reduce the “lag time” developers experience between waiting for the code to be built and for resources to be provisioned to build an environment to test one or more portions of code, and can provide a less costly alternative to maintaining and operating dedicated environments.

FIG. 1 is a functional block diagram of computing environment 100, in accordance with an embodiment of the present invention. Computing environment 100 includes server computer system 102 and client computer system 110. Server computer system 102 and client computer system 110 can be desktop computers, laptop computers, specialized computer servers, or any other computer systems known in the art. In certain embodiments, server computer system 102 and client computer system 110 represent computer systems utilizing clustered computers and components to act as a single pool of seamless resources when accessed through network 114. In general, server computer system 102 and client computer system 110 are representative of any electronic devices, or combination of electronic devices, capable of executing machine-readable program instructions, as described in greater detail with regard to FIG. 5.

Server computer system 102 includes provisioning program 104 and task repository 106. Provisioning program 104 monitors task repository 106, and allocates resources from resource pool 108 via network 114 to build environments for various coding tasks. Provisioning program 104 further calculates a time at which to start building environments for coding tasks, such that the environments are built when the user is prepared to test the one or more portions of code in the environments. The term “environment”, as used herein, refers generally to an environment used to test code written for, and/or otherwise affected by, a coding task. An environment may be, for example, a test environment built specifically to test one or more portions of code, a staging environment (e.g., pre-production environment), and/or an actual production environment (i.e., where code is ultimately deployed and made available for use by end users).

Task repository 106 stores tasks received from project management tracking tool 112 via network 114. Task repository 106 can be implemented using any non-volatile storage media known in the art. For example, task repository 106 can be implemented with a tape library, optical library, one or more independent hard disk drives, or multiple hard disk drives in a redundant array of independent disks (RAID). Similarly, task repository 106 can be implemented with any suitable storage architecture known in the art, such as a relational database, an object-oriented database, and/or one or more tables.

Resource pool 108 comprises hardware and software resources to be allocated by provisioning program 104 when building an environment for a coding task. For example, resource pool 108 may comprise a plurality of computer systems with various software installed thereon, coupled to a plurality of databases and/or other devices. In general, resource pool 108 represents any hardware, software, and combinations thereof that may be provisioned for building an environment with which to test programming code written for, and/or otherwise affected by, one or more coding tasks. For example, resource pool 108 may include a plurality of web servers, client computer systems, and web browsers that can be provisioned to build environments to test program code of a web application.

Network 114 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and include wired, wireless, or fiber optic connections. In general, network 114 can be any combination of connections and protocols that will support communications between server computer system 102, resource pool 108, and client computer system 110, in accordance with a desired embodiment of the invention.

Client computer system 110 includes project management tracking tool 112. Project management tracking tool 112 enables a user to create and define coding tasks. A coding task involves creation and/or modification of one or more portions of code of one or more software programs. Project management tracking tool 112 communicates with server computer system 102 via network 114 (e.g., using TCP/IP) to store task information in task repository 106. Task information describes one or more portions of a software program that needs to be created and/or modified. For example, project management tracking tool 112 can be implemented with any program that provides an integrated environment for creating and storing one or more coding tasks, monitoring its progress, and coordinating between one or more developer teams.

FIG. 2 is a flowchart 200 illustrating operational steps for creating a coding task, in accordance with an embodiment of the present invention.

In step 202, project management tracking tool 112 receives task information for the coding task being created. In this embodiment, task information is received from a user of client computer system 110. Task information comprises a title, a brief description of the coding task, what type of code needs to be written, areas of the software program affected by a coding task, and a default status of “not started”. For example, the title of the coding task could be “Modification of Web Application Module”. A brief description could specify that the module that allows access to a database is malfunctioning, while the area of the software program affected could indicate that the entire web application, the module that allows access to a database, and the servers that host the web application are areas affected by the coding task. The task information can further specify that code for the module needs to be rewritten or otherwise modified, and the time estimated to complete the coding task is 4 hours.

In step 204, project management tracking tool 112 receives the identified length of time to complete coding task (T_(CT)) for the coding task being created. T_(CT) represents the length of time it takes to complete a coding task (i.e., 4 hours to complete writing code for a module to access a database). In this embodiment, T_(CT) is received from a user of client computer system 110. For example, a user creating the coding task may specify an estimated time on the order of 4 hours, 8 hours, or 16 hours.

In step 206, project management tracking tool 112 creates and transmits the coding task to server computer system 102 via network 114 for storage in task repository 106. In this embodiment, after performing the operational steps of FIG. 2, a user responsible for completing the coding task can subsequently access the created coding task in task repository 106 to begin work on the coding task.

FIG. 3 is a flowchart 300 illustrating operational steps for building an environment for a coding task stored in task repository 106, in accordance with an embodiment of the present invention. For illustrative purposes, the following discussion is made with respect to a single example coding task and building of a test environment for the coding task, it being understood that the operational steps of FIG. 3 may be performed for a plurality of different coding tasks, and the environment built can be any desired type of environment.

In step 302, provisioning program 104 detects that a coding task stored in task repository 106 has changed to an “in-progress” status. In this embodiment, each coding task stored in task repository 106 is associated with a status that indicates it state. Statuses can include, “not started”, “in-progress”, and “completed”. In this embodiment, provisioning program 104 queries task repository 106 pursuant to a schedule to determine whether any coding task statuses have changed from “not started” to “in-progress”, which indicates that a user has begun work on a coding task. In alternative embodiments, provisioning program 104 can receive indications of status changes directly from another program, such as from project management tracking tool 112.

In step 304, provisioning program 104 identifies areas of the software program affected by the coding task. In this embodiment, provisioning program 104 identifies areas of the software program affected by the coding task by accessing task repository 106 and analyzing the task information for the coding task. As previously discussed, a user who created the coding task may have specified one or more affected areas of the software program which provisioning program 104 can identify in step 302. In addition, provisioning program 104 can analyze task information, such as the title and brief description of the coding task, to identify affected areas of the software program. For example, by analyzing a title of “Modification Web application Module” and a description specifying that the web application module must be modified such that it properly accesses a database, provisioning program 104 can identify areas of the software program affected by the coding task as including the web application module and other portions of code involved in accessing the subject database.

In step 306, provisioning program 104 predicts a necessary environment for the coding task. Predicting a necessary environment for a coding task involves identifying resources in a resource pool needed to create an environment for testing program code written for, and/or otherwise affected by the coding task. In this embodiment, provisioning program 104 accesses task repository 106 for the task description transmitted to task repository 106 to calculate the necessary environment based on the identified areas of the software program affected by the coding task. For example, where the coding task involves writing code for a web module that accesses a database, provisioning program 104 identifies that a plurality of servers are coupled to a database, and configures those resources with the necessary software, settings, and operational parameters that are needed to test the functionality of the web module. In alternative embodiments, provisioning program 104 could also predict the necessary environment based on any specific resources indicated by a user who created the coding task, or based on environments that have been historically needed for similar coding tasks, or any combination thereof.

In step 308, provisioning program 104 calculates a time at which to start testing (T_(TST)). T_(TST) represents the predicted time when one or more portions of code will be ready for testing. In this embodiment, provisioning program 104 calculates T_(TST) by adding an identified user start time (T_(US)) at which a user responsible for completing the coding task begins work on the coding task, an identified length of time it takes a user to complete a coding task (T_(CT)), and an identified length of time it takes for the code to be compiled into an executable program (T_(BC)). For example, provisioning program 104 might identify the values it needs as, T_(US) to be 9:00 am, T_(CT) to be 2 hours, and T_(BC) to be 3 hours. Provisioning program 104 would then calculate T_(TST) by adding the values for T_(CT) and T_(BC) (2 hours plus 3 hours), and adjusting T_(US) (9:00 am) by 5 hours (T_(CT)+T_(BC)) to give a T_(TST) of 2:00 pm.

In this embodiment, provisioning program 104 identifies T_(US) as the time a user responsible for completing the coding task accesses the created coding task in task repository 106 to begin work on the coding task, which causes the coding task status to switch from “not started” to “in-progress”. In alternative embodiments, provisioning program 104 can receive an indication from project management tracking tool 112 when the user begins work on the coding task and use that time as T_(US). In other embodiments, provisioning program 104 could confirm T_(US) with project management tracking tool 112 before proceeding. For example, provisioning program 104 could query project management tracking tool 112, which in turn prompts the user of project management tracking tool 112 to input T_(US).

In this embodiment, provisioning program 104 identifies T_(CT) as the length of time to complete the coding task by accessing stored task information in task repository 106 which contains a user identified length of time to complete coding task.

In this embodiment, provisioning program 104 uses historical data to identify T_(BC). Historical data in this example could be the stored data from previous builds (i.e., how long it took to build a type of code). For example, provisioning program 104 uses historical data, and it indicates that it took 2 hours to build that code; then provisioning program 104 sets that value as T_(BC).

In step 310, provisioning program 104 determines whether an environment for the coding task will be available for use (i.e., potentially obviating the need to build the predicted environment). An environment can be regarded as available for use if it is currently in use but will be available at T_(TST) or within a specified amount of time from T_(TST). An environment can also be regarded as available if it will be in use at T_(TST) but can be simultaneously used to test the completed coding task. In this embodiment, provisioning program 104 accesses resource pool 108 to determine whether an environment will be available for use. For example, provisioning program 104 could access resource pool 108 and identify that a particular environment comprising the needed resources for the coding task is currently in use but will be available within five minutes after T_(TST).

If, in step 310, provisioning program 104 determines an environment will be available for use, then, in step 312, provisioning program 104 reserves the environment for testing the one or more portions of program code for the completed coding task. In this embodiment, reserving the environment prevents allocated resources of the environment from being reallocated for other purposes, and also prevents the environment from being reserved by other applications. For example, provisioning program 104 may determine that a particular environment for a first coding task is already built and will be available for use at T_(TST) for a second coding task. Provisioning program 104 would then prevent resources of that environment from being reallocated for other purposes, and also prevent that environment from being reserved by other applications.

If, in step 310, provisioning program 104 determines an environment is not available for use, then, in step 314, provisioning program 104 predicts a time at which to start building the environment for the coding task (T_(SBE)). In this embodiment, provisioning program 104 predicts T_(SBE) by subtracting the identified length of time to build an environment (T_(BE)) which represents the identified length of time needed to identify and allocate resources in resource pool 108 and configure those resources to test one or more portions of program code written for, or otherwise affected by, the coding task from T_(TST). For example, provisioning program 104 might identify TST as 2:00 pm and T_(BE) as one hour. Provisioning program 104 would then calculate T_(SBE) by adjusting TST (2:00 pm) by T_(BE) (one hour) to yield a T_(SBE) of 1:00 pm.

In this embodiment, provisioning program 104 uses historical data to identify T_(BE). Historical data includes saved times for how long provisioning program 104 took to build environments for one or more previous similar coding tasks. For example, when identifying T_(BE) for a coding task that called for a modification to a module for a web application, provisioning program 104 can check historical data to determine how long it previously took to provision resources to build similar environments and use that values as T_(BE). Other embodiments can use other techniques, such as using preset values based on resources (e.g., preset of X minutes for each server that must be provisioned, and Y minutes for each database), and adding those values to arrive at T_(BE). For example, provisioning program 104 might identify a server (preset value of 40 minutes to build) and a database (preset value of 20 minutes to build) are needed for the environment. Provisioning program 104 could then identify T_(BE) by adding those values for a server and a database (40 minutes+20 minutes) to give T_(BE) a value of 60 minutes.

In step 316, provisioning program 104 determines whether needed resources are available to build the environment for the coding task. In this embodiment, provisioning program 104 accesses resource pool 108 and checks whether the resources identified in step 306 will be available by T_(SBE). For example, provisioning program 104 might predict that T_(SBE) for a coding task is 1:00 pm. Provisioning program 104 would then access resource pool 108 and determine whether the needed resources will be available at 1:00 pm (e.g., needed resources will not be allocated for another environment at 1:00 pm, and/or needed resources will be allocated but can be shared).

If, in step 316, provisioning program 104 determines that needed resources are not available to build the environment for the coding task, then, in step 318, provisioning program 104 alerts the user. In this embodiment, the alert indicates that resources will not be available. Accordingly, a user could then decide to work on another task. In other embodiments, provisioning program 104 could identify tasks for which environments or resources would be available for testing if the task was started now. For example, provisioning program 104 could access task repository 106, identify the “not started” tasks, and perform the previously discussed steps as if the “not started” tasks were just started.

If, in step 316, provisioning program 104 determines that needed resources are available to build the environment for the coding task, then, in step 320, provisioning program 104 starts building the environment for the coding task at T_(SBE). In this embodiment, provisioning program 104 builds the environment by provisioning and configuring resources for the coding task from resource pool 108 at T_(SBE).

Accordingly, in this embodiment, provisioning program 104 starts building an environment for the coding task so that the environment is built and ready for testing by the time the coding task is completed. In some instances, provisioning program 104 may identify an existing environment that can be used for the coding task, obviating the need to build another environment. Thus, this embodiment can be used to provision resources from a resource pool in a more efficient way and reduce “lag time” developers experience while waiting for an environment to be built.

FIG. 4 is a flowchart 400 illustrating operational steps for predicting a time at which to start building an environment, in accordance with an embodiment of the present invention. For example, operational steps of flowchart 400 can be performed at step 314 of flowchart 300. For illustrative purposes, the following discussion is made with respect to a single example coding task and building of a test environment for the coding task, it being understood that the operation steps of FIG. 4 may be performed for a plurality of different coding tasks, and the environment built can be any desired type of environment.

In step 402, provisioning program 104 calculates a tentative start time (T_(TS)), which is an initial calculation of a time to start building the environment. In this embodiment, provisioning program 104 uses T_(US), T_(CT), T_(BC), and T_(BE) as values to calculate T_(TS). Provisioning program 104 calculates T_(TS) by adjusting the value for T_(US) by adding T_(CT) and T_(BC) and subtracting T_(BE). For example, provisioning program 104 might identify the values it needs as T_(US) to be 9:00 am, T_(CT) to be 2 hours, and T_(BC) to be 3 hours and T_(BE) to be 4 hours. Provisioning program 104 would then calculate T_(TS) by adding the values for T_(CT) and T_(BC) (2 hours plus 3 hours), subtracting that value by T_(BE) (5 hours minus 4 hours) and adjusting T_(US) (9:00 am) by 1 hour (T_(CT)+T_(BC)−T_(BE)) to give T_(TS) value of 10:00 am. In alternative embodiments, provisioning program 104 could use other values to determine T_(TS).

In step 404, provisioning program 104 determines whether (T_(TS)+T_(BE)) complies with a user's schedule. The value of (T_(TS)+T_(BE)) represents the time at which the environment would be finished being built (i.e., finished allocating and configuring necessary resources, such that code written for, or otherwise affected by, the coding task can be tested), if building the environment began at T_(TS). A user's schedule represents the available times that a user can begin testing one or more portions of code using the built environment. In an alternative embodiment, provisioning program 104 identifies the user schedule from historical data which indicates times a user has previously been available to begin testing. For example, if provisioning program 104 determined (T_(TS)+T_(BE)) to be 2:00 pm, provisioning program 104 would compare whether the user schedule provided by historical data indicates that the user will be available to work at 2:00 pm. In alternative embodiments, provisioning program 104 could receive indications from project management tracking tool 112 for user schedules. Alternatively, provisioning program 104 could access user schedules from another program, such as a shared calendar program.

If, in step 404, provisioning program 104 determines that the value of (T_(TS)+T_(BE)) complies with a user's schedule, then, in step 406, provisioning program 104 sets T_(TS) as the time to start building the environment (T_(SBE)). T_(SBE) represents the predicted time to start building the environment so that the environment is ready for use when the user is available to begin testing.

If, in step 404, provisioning program 104 determines that (T_(TS)+T_(BE)) does not comply with a user's schedule, then, in step 408 provisioning program 104 determines a next available time to begin testing (T_(NA)), which is the earliest available time that the user can begin testing one or more portions of code using the built environment, and sets T_(SBE) as (T_(NA)−T_(BE)). In this embodiment, provisioning program 104 identifies T_(NA) using the same historical data and/or schedule that was checked in step 404 and sets that value as T_(TS). For example, if a user consistently begins work at 9:00 am, provisioning program 104 can use that value as the earliest available time a user can begin testing one or more portions of code using the built environment. In alternative embodiments, provisioning program 104 prompts the user of project management tracking tool 112 to input earliest available time to start provisioning and sets that value as T_(NA). Provisioning program 104 then subtracts the value for T_(BE) from the value for T_(NA) to and sets the resulting value as T_(SBE). For example, if provisioning program 104 determined T_(NA) to be 2:00 pm and T_(BE) to be two hours, provisioning program adjusts T_(NA) by subtracting two hours to yield a T_(SBE) of 12:00 pm.

Accordingly, by performing the operational steps of FIG. 4, provisioning program 104 calculates T_(SBE) for the coding task such that the environment is available to the user when the user and code are ready for testing; which, again, can reduce the “lag time” the user experiences between waiting for an environment to be built for testing programming code written for, and/or otherwise affected by the coding task. Provisioning program 104 can also calculate a T_(SBE) for the coding task based on user availability such that the environment is not prepared too far in advance so as to create “lag time” for other users who might need those resources.

FIG. 5 depicts a block diagram of components of computer system 500 which is representative of the computer systems of FIG. 1, in accordance with an illustrative embodiment of the present invention. It should be appreciated that FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made. In general, the components illustrated in FIG. 5 are representative of any electronic device capable of executing machine-readable program instructions.

Computer system 500 includes communications fabric 502, which provides communications between computer processor(s) 504, memory 506, persistent storage 508, communications unit 512, and input/output (I/O) interface(s) 514. Communications fabric 502 can be implemented with any architecture designed for passing data and/or control information between processors (such as microprocessors, communications and network processors, etc.), system memory, peripheral devices, and any other hardware components within a system. For example, communications fabric 502 can be implemented with one or more buses.

Memory 506 and persistent storage 508 are computer-readable storage media. In this embodiment, memory 506 includes random access memory (RAM) 516 and cache memory 518. In general, memory 506 can include any suitable volatile or non-volatile computer-readable storage media.

From communications unit 512, the software and data can be loaded onto persistent storage 508.

I/O interface(s) 514 allows for input and output of data with other devices that may be connected to server computer system 102. For example, I/O interface 514 may provide a connection to external devices 520 such as a keyboard, keypad, a touch screen, and/or some other suitable input device. External devices 520 can also include portable computer-readable storage media such as, for example, thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, e.g., provisioning program 104, can be stored on such portable computer-readable storage media and can be loaded onto persistent storage 508 via I/O interface(s) 514. I/O interface(s) 514 also connect to a display 522.

Display 522 provides a mechanism to display data to a user and may be, for example, a computer monitor.
